Effect of Heavy Fuel Oil/Natural Gas Co-Combustion on Sulphur Trioxide and other Pollutants Generation

The purpose of this paper is to examine effect of co-combustion of heavy fuel oil and natural gas on the pollutant formation: SO3, CO2, SO2, NOX and soot. The analysis was carried out by means of numerical simulations on the case of commercial steam generator furnace of TPP Sisak. Comprehensive mathematical model with detailed 3D mesh was set up to include all relevant aerodynamic and thermo-chemical processes in the furnace. Dedicated model for SO3 formation was developed earlier and used in this work. By increasing the natural gas contribution in overall fuel fired in the furnace, emissions of CO2, SO2, soot, NOX and SO3 decreased. Heat transferred to the furnace walls and temperature field in the furnace were also examined.
